My invention relates to a novel hinged box and cover device.

The object of my invention is to provide a box comprising a box receptacle and cover therefor with a hinge guard between the box receptacle and the cover, said hinge guard being so constructed as to limit the extent to which the cover may be hingedly lifted from the receptacle and so deformed upon a cover-closing operation as to assume such a position in full box-closed condition as to provide a resistance against a coveropening motion.

Another object of my invention is to provide in a single unitary blank for the formation of a box cover structure means whereby the cover may be hingedly connected to the box receptacle and provided with a hinge guard.

In the drawing:

Figure 1 is a plan view of a box blank made in accord with my invention.

Figure 2 is an isometric view of a box formed from the. blank shown in Fig. 1 and disclosed in cover-closed position.

Figure 3 is an isometric view of the box shown in Fig. 2 with the cover in open position and the hinge guard in position for 'a box-closing operation.

Figure 4 is a front elevation of the box shown in Figure 3 with the cover partially closed and the hinge guard in partially folded position.

Figure 5 is a perspective view of a box made in accord with my invention and shaped somewhat differently.

Like parts are identified by the same reference characters throughout the several views.

The boxproduced by my improved blank is preferably formed of fairly stilf cardboard or other suitable sheet material having characteristics which will permit of the resilient deformation of the hinge guard 50 which comprises probably the most important structural elementpertaining to my invention.

In its major structural elements my box comprises a box receptacle l and a box cover ll hingedly connected to the receptacle along one margin l2.

I have shown my improved box in Figs. 1 to 4 inclusive in the form of a box usable for matches, since the form thereof includes wide and narrow panels for sides and edges respectively of the box in a contrasting relation which facili-- tates the description herein, whereas the box shown in Fig. 5, likewise usable for old style matches for home use, illustrates the slight change in the configuration of the hinge members 50 necessitated by the change in the general shape of the box.

The blank sheet of material shown in Fig. 1 is cut and scored as required for the formation of the box shown in Figs. 2, 3 and 4, and includes centrally disposed panels l3, l4, l and i6 respectively. The panel [3 may be referred to as a tab and comprises an extension of panel M which in the completed box forms the back of the box receptacle ill, the tab l3 being folded 319 along a score line H at right-angles to the panel M to provide a reinforcement and connection with panels l8 and I9 which in superimposed relation form the bottom of the box receptacle. Tab comprises an extension of panel 2| which, with panel 22, forms the double wall front of the receptacle in the completed box, and tab 20 in the completed box is folded at right-angles to panel 2| along the score line 23 so that the tab may extend along the bottom of the receptacle 20 and form a reinforcement therewith.

Panel l5 forms the top of the cover of the box and is connected with panel it along a score line 24 which comprises the hingedconnection between the top or cover and the box receptacle 25 l0.- Wing panels 25 and 26 become the side panels of the cover of the box and are of identical dimensions with reinforcing wing panels 21 and .28 which, when folded 'in conjunction with the panel I6 which forms the front'of the cover of the box, may be swung along the score lines 29 and 30 to a position in which they are superimposed upon the panels 25 and 26 so that in the completed box as shown probably most clearly in gFig. 3, the sides of the cover of the box are double in thickness.

It will be noted, as indicated, that the double lines at 3| and 32, between panels 25 and 21 on the one hand, and 2B and 28 on the other, represent a kerf which permits of the folding of the panels so that 21 may overlay 25, and 28 may overlay 26 when the wing panels 21 and 28 are adjusted upon the score lines 29 and 30 and the panel I6 is adjusted upon score line 33 to its ultimate position with reference to panel l5 along score line 33.

Panels 34 and 35 become side panels for the box receptacle Ill-when they are adjusted upon score lines 36 and 31 which constitute the margin lines of the back panel 14.

From the above description of the blank as shown in Fig. 1, it will be apparent to those skilled in the art how the blank is adjusted to form the box shown in Figs. 2, 3 and 4. With the box formed in this manner the hinge guards extending between score lines 38 and 39 are of such dimensions and so disposed that when the cover II is open, the hinge guard is substantially plane except for slight curvature induced by previous bending operations as indicated clearly in said Fig. 3. When, however, as indicated in Fig. 4, the cover is in an intermediate position in a closing operation, the hinge guards 50 are forced to bend inwardly and they assume a position within the confines of the cover whilethe cover is in an intermediate position between full close and full open position.

Then, as the cover is moved downwardly upon the box receptacle ID, the guards unfold until in full closed position they are fully extended once more, but this time in a position extending downwardly from the upper margins 39 of the box receptacle and, being in a confined relation to the side walls 25 and 26 of the cover II and side walls 34 and 35 of the box receptacle l0, any attempt to open the cover once more is resisted by the hinge guards 50. It is only by brute force sufiicient to distort the side walls of the cover and receptacle that it is possible to open the cover once more, since in the folding and unfolding motion of the hinge guards 50 there must be additional room between the side walls of the cover and receptacle. Obviously, since the receptacle is usually filled or partially filled with matches or other comparatively incompressible substances carried by the receptacle, it is largely distortion of the cover which permits the folding and unfolding of the hinge guards, and it will be noted that the side walls of the cover II are double walls by reason of the coincidence of the panels 25 and 21 on the one side and 26 and 28 on the other.

In the formation of a box structure of shape diifering from that shown in Figs. 1 to 4 inclusive, I may form my improved box as shown in Fig. 5, in which the box receptacle instead of being cut away'at 40, is substantially rectangular throughout and the hinge guards 5| extend forwardly at 52 to the front edge 4| of the box.

As a result of the construction shown in my drawing in accord with my invention, it will be found that a box provided with hinge guards 50 or 5| will resist opening of my box and will also tend to hold the cover in substantially open position, and since the guards may be formed as shown most clearly in Figs. 3 and 5, they are not in a position to interfere with the removal of the contents of the box receptacle.

I have found that the hinge guard 50 or 5| operates successfully partly by reason of the acute ular relationship of the top margin 39 of the box and the margin 38 of the cover. When the cover is in completely opened or completely closed position it thus means that the guard 50 provides an area such that it may be easily deformed within the dimensions of the cover and box.

I claim:

1. A box of paper-like material including a body, a cover hinged to the body and provided with side walls, at least one of which is braced against lateral movement, and a resilient side member of paper-like material connecting the cover and body and foldable to and from a position between the body and said braced wall of the 'cover in closing and opening the latter and operating through its resiliency to resist movement of the cover from open and closed positions.

2. A box of paper-like material includinga body, a cover hinged to the body and provided with side walls, at least one of which is braced against lateral movement, and a resilient side member of paper-like material connecting a body wall and said braced wall of the cover and foldable to and from a position between said walls in closing and opening the cover and operating through its resiliency to resist movement of the cover from open and closed positions.

3. A box of paper-like material including a body, a cover hinged to the body at the back thereof and provided with connected front and side walls, and a resilient side member of paperlike material connecting the cover and the body and foldable to and from a position between the body and a side wall of the cover in closing and opening the latter and operating through its resiliency to resist movement of the cover from open and closed positions.

4. A box of paper-like material including a body, a cover hinged to the body at the back thereof and'provided with connected front and side walls, and a resilient substantially triangular-shaped side member of paper-like material connecting the cover and the body and having a spring bend disposed transversely of the box and intermediate of the member, said member being foldable to and from a position between the body and a side wall of the cover in closing and opening the latter and operating through'its resiliency to resist movement of the cover from open and closed positions.

5. A box formed from an integral blank and comprising a body, a cover hinged to the body along a rear margin thereof and provided with side walls and a front wall connecting the side walls, and a resilient side member marginally joined to a body wall and a side wall of the cover and foldable to and from a position between said walls in closing and opening the latter and oper- 40 ating through its resiliency to resist movement of the cover from open and closed positions.

6. Abox formed from an integral blank and comprising a body having upstanding side walls and an upstanding rear wall permanently bonded to the side walls, a cover having connected front and side walls and hinged to the body along its rear margin, and a hinge guard comprising a resilient foldable side memberadapted to prevent excessive hinge movement and ,foldable in a cover-closing operation to a position between a side wall of the cover and a side wall of the body, whereby to assume a plane position between said side walls and resistant to a cover-opening operation.

'7. A box formed from an integral blank and comprising a walled body, a cover provided with side walls of double thickness and a front wall connecting the side walls, and a hinge guard integral with a side wall of the box and integral with one thickness of a side wall of the cover, whereby to limit the hinged movement of the cover with respect to the body, said hinge guard being deformable in a box-closing operation, whereby to permit the side walls of the cover to assume an overlying relationship to the side walls of the body, said hinge guard in the closing movement ofjsaid cover being received between side walls of the cover and body respectively, the double wallof the cover providing resistance to the deformation of the hinge'guar d in a box-opening operation.
